Research in the field of assisted reproduction provides us with more and more answers to situations which previously had none. It gives us solutions, options and new ways of overcoming the many difficulties which arise in reproduction. What’s more, progress in science also helps diagnosis and treatment to be increasingly specific, personalised and individual. In fact, we might even say that the aim is to reach a point where one of a kind treatments are designed for one of a kind patients. Continue Reading »
The social changes in recent years have been highly beneficial to achieving rights and equalities, although it has also led to a significant increase in maternal age. But nature does not understand social change and the biological clock keeps ticking as usual. There are several consequences of this delay on female fertility and it depends on each woman, but it is a reality that as women age, the ovarian reserve diminishes and the egg quality lowers.

Assisted Human Reproduction is undoubtedly an area with ethical and moral implications. There are common issues that arise with the generation of new embryos when a couple undergoes ART and with transfers of previously frozen embryos. Some of the most frequent issues are: embryo manipulation and genetic diagnosis; the use of donor gametes and the possible coexistence of their legal children with the biological ones in the future; the option of discarding embryos by parents for no other purpose when they don’t wish to donate them to other couples with reproductive problems or for research purposes; the age of women accessing ART, along with a long list of legal, ethical and moral issues pertinent to each assisted reproduction centre.

This is not science fiction, it’s reality. It is reproductive medicine and advanced genetics together to achieve healthy children who are free of diseases. Before, medicine focused on a person’s health. Now thanks to genetics and scientific research we are able to go one step further and take care of the embryo. Continue Reading »
It is estimated that about 20% of reproductive problems are genetic or chromosomal type. That is why today genetic testing is an essential part of the fertility study in couples who come to our clinic looking for descendants.
For the diagnosis of fertility problems there is a set of genetic studies very useful in the assistance of couples with reproductive desire. Tests such as the karyotype in both partners, microdeletion of the Y chromosome in the male or the molecular study of fragile X syndrome in women are usually required tests to determine a possible genetic basis of fertility problems in couples.

Currently, oocyte donation is probably the most demanded technique in fertility centers, mainly due to the increase of maternal age. Voluntary participation of donors is essential, but donors must be evaluated carefully in order to avoid unsatisfactory results (do not forget that the ultimate goal is the birth of a healthy child without prejudice to the donor or the recipient couple).
In a recent study carried out in our center and presented at the Congress of the British Fertility Society, the leading causes of rejection in our program were evaluated in 560 potential egg donors. Continue Reading »
Genetic Amniocentesis is a prenatal diagnostic technique aimed at obtaining fetal karyotype. The karyotype is the number of chromosomes that are endowed with all people. Normal people we have 46 chromosomes distributed in 23 pairs (22 pairs of chromosomes called autosomes and 1 pair of sex chromosomes, XX or XY, which determine the sex of the fetus). Down syndrome or trisomy 21 is the most common chromosomal abnormality in new born infants; in this case, the individual has 47 chromosomes, and the alteration is that there are 3 21 chromosomes rather than two.

Today, in In Vitro Fertilization treatments, it is not extraordinary to find ourselves on the day of embryo transfer with a high number of good quality embryos. For a fresh transfer we shall be electing the embryo or embryos that morphologically and kinetically demonstrate greater development and ‘the other’ good quality ones can be cryopreserved.

From fertilization and until the embryo transfer takes place in the womb, embryos follow a development that is valued by embryologists daily. Those embryos that have kept a correct evolution and are in better condition are selected to be transferred. Continue Reading »
Before establishing the biological origin differences between identical and fraternal twins, let’s make a quick note on the etymology of both words.
Etymologically both terms have the same origin (Latin gemellicium) and were used interchangeably to refer to children born in the same delivery. The only difference was the use of the term fraternal twin in the popular speech twin and identical twin in the cultivated speech. However, the semantic evolution of both words has been accompanied by the numerous advances in the field of genetics and knowledge of the development of the human embryo. In fact, since they differ in the latest edition of the dictionary of the RAE: Continue Reading »
The information that we can offer online does not replace the direct professional opinion of the doctor after a comprehensive assessment of your personal case and medical history. Therefore, we encourage your to request an appointment with our medical team either in person or through an online video conference if you are unable to travel to one of our clinics in Alicante, Elche, Cartagena or Benidorm.
